Today I designed and printed a part for a vacuum cleaner. The original tips were too big and I couldn't clean up some nooks and crannies. In my case, this larger tip is used for cleaning radiators, and this smaller cap helps clean under the bed. The diameter of the entrance to the vacuum cleaner is 32 mm. The dimensions of the tip are 32x12mm.

I had to build a housing for the radiators we almost never use. In case there should occur minor inspections and for a minimum of ventilation we needed a grille of the required soze and looks - so I designed a frame that can be glued into the drywall opening that fits the grille perfectly. This is a quick first version - we printed and installed eight items. It will be tested now and evnetually be improved, Depending on your settings the parts might need a little bit of sanding to fit properly.

This tool fit on many radiators and prevent small black splashes on a new painted wall. It's waterproof and can be printed without support. You can use most of the raditor bleeding keys with it. I made this for private use with Sketchup and want it to share with you. Heizkörper-Entlüftungshilfe. Kann direkt an den Heizkörper gehängt werden um das Wasser aufzufangen. So entstehen keine schwarzen Spritzer und das Wasser landet direkt darin.

In imaging applications based on RF Tomography coupling between transmitters and receivers is a principal technical challenge to be overcome. To mitigate the coupling, we propose to activate different transmitters simultaneously, and determine their respective current source distribution in order to create electric field nulls at desired points (e.g., the receivers). The current design problem must take into consideration physical and system constraints of the radiators. As such, the current...

Spacecraft designed for missions beyond low earth orbit (LEO) face a difficult thermal control challenge, particularly in the case of crewed vehicles where the thermal control system (TCS) must maintain a relatively constant internal environment temperature despite a vastly varying external thermal environment and despite heat rejection needs that are contrary to the potential of the environment. A thermal control system is in other words required to reject a higher heat load to warm...

The antenna subtraction method handles real radiation contributions in higher order corrections to jet observables. The method is based on antenna functions, which encapsulate all unresolved radiation between a pair of hard radiator partons. To apply this method to compute hadron collider observables, initial-initial antenna functions with both radiators in the initial state are required in unintegrated and integrated forms. In view of extending the antenna subtraction method to...

The Ultralight Fabric Reflux Tube (UFRT) was developed by Pacific Northwest Laboratory (PNL) as a lightweight radiator concept to be used on planetary-type missions (e.g., Moon, Mars). The UFRT consists of a thin-walled tube (acting as the fluid boundary), overwrapped with a low-mass ceramic fabric (acting as the primary pressure boundary)....

Experimental results are highly dependent upon shield configuration and cannot be extrapolated...

Since the vertical dryer stands for soda stream bottles I found kinda lacked airflow, I designed this hook to fit to my towel radiator. It is designed to fit to radiator tubes up to 21mm (roughly 13/16") diameter. But I also included the Fusion360 file so you can modify it yourself. Or just write me a comment with your desired diameter and I modify it for you. The bottom latch is for pushing against the hook if the bottle is stuck. But I designed the bottle fitment rather loose so that...

Temperature and size considerations of the tube fin space radiator were characterized by charts and equations. An approach of accurately assessing rejection capability commensurate with a phase A/B level output is reviewed.

The program also handles the flow and thermal considerations of the film coefficient.

During Space Transportation System (STS) flight 121, higher than predicted radiator outlet temperatures were experienced from post insertion and up until nominal correction (NC) burn two. Effects from the higher than predicted heat loads on the radiator panels led to an additional 50 lbm of supply water consumed by the Flash Evaporator System (FES). Post-flight analysis and research revealed that the additional heat loads were due to Free Molecular Heating (FMH) on the radiator panels, which...
